SUSPENDER-LOCK.

Specification of Letters Patent.

Patented June 29, 1915..

Application filed October 7, 1913. Serial No. 793,860.

To all whom it may concern Be it known that we, EDWARD KLATT andRnINiioLo KALrIns'r, (who have declared their intention of becomingcitizens ofthe United States) residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Suspender- Locks; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention relates to new and useful improvements in suspender locksand resides in the provision of a lock which will enable readyadjustment of suspenders and the like and afford eilicient locking meansfor locking the suspender straps after adjustment.

An important object of the invention is to provide a device such asdescribed which will efiiciently permit the adjustment and locking ofthesuspenders without injury thereto.

A further object is to provide a device such as described which may bereadily attached to the suspenders, consists of few parts, cheap tomanufacture and which possesses the capacity for long and repeatedservice.

The above and additional objects are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification and then more (particularly pointed out in the claim whichis appended hereto and forms a part of this application.

With reference to the drawings, wherein we have illustrated thepreferred embodil1nent of our invention as it is reduced to practice,and throughout the several views of which, similar reference numeralsdesignate corresponding parts, Figure 1 is a side elevation illustratingour device as it would appear in assembled operative position. Fig. 2 isa vertical sectional view taken on line 22 of Fig. 1 illustrating thedevice in locked position and attached to the suspenders Fig. 3 is aside elevation illustrating 0 lthe device removed from the suspendersand a locking plate in open position, and Fig. 4: is a side elevationillustrating the locking plate in closed position.

Referring to the drawings 1 designates \one of the straps of theordinary suspender or the like that is double at its lower terminal andconnected with the usual securing straps not shown.

The adjusting locking device consists of a rectangular plate 9- formedof any suitable metallic material that forms the body portion for thedevice. This rectangular plate 2 or body portion is provided adjacentits lower longitudinal edge with a longitudinal slot 3. The freeterminal of the strap 1 of the suspenders is inserted through thislongitudinal slot 3 as at 4: and suitably stitched as at 5 thus securingthe strap 1 to the device. A pair of gripping tongues 6 and 7 are formedwith the body plate 2 in spaced relation to each other by longitudinallyslitting the plate. These gripping tongues 6 and 7 are bent inwardly andare c isposed at an angle of 45 degrees to the plate 2 so as to providefor the gripping engagement with the suspender strap 1. An approximatelyU-shaped locking bar 8 is pivotally mounted within one of a pair ofrolled ears 9 and 10 at one terminal and at its other terminal within aflanged portion 11. These ears 9 and 10 are formed integral with theplate 2 at one end thereof in spaced relation to each other and arerolled at their upper terminals for a purpose which will be hereinafterdescribed. The locking bar 8 is offset as at 12 at its pivoted terminalsso as to provide for the positioning of the bar 8 between the angularlydisposed gripping tongues 6 and 7. The portion 1 of the suspendersextends between the locking bar 8 and the locking tongues 6 and 7 sothat when the locking bar 8 is moved so as to interpose the tongues 6and 7 the suspender portion 1 is forced into gripping engagement withthe tongues.

A locking plate 13 having a rolled ear 14: formed adjacent its innerterminal and an integrally formed spring catch 15 at its outer terminalis pivotally mounted upon the plate 2. The rolled ear i l on the lockingplate is positioned between the rolled ears 9 and 10 and a hinge pin 16is inserted through each of the rolled ears 9, 10 and 14; thus providinga hinged joint for the plate 2 and locking plate 13.

The rolled ear 1% extends approximately at right angles to the plate 13thus providing for the disposal of the plate 13 in close relation to theplate 2 when in a closed position. The flanged portion 11 is formedintegrally with the plate 2 and extends at right angles thereto. Alocking head 17 is formed integrally with the outer terminal of theflanged'portion 11 and is provided by rolling the outer terminal of theflange back upon itself upon the outer side thereof. This bead 17 isdisposed adjacent one end of the flange so as not to interfere with thepivoted terminal of the locking bar 8 that is mounted within the flange.

It is apparent with reference to the foregoing description and drawingsthat when the locking bar 8 is not held in looking position by thelocking plate 13 that the suspenders are permitted adjustment. To lookthe suspenders in adjusted position, the looking bar 8 is moved so as toforce the portion 1 of the suspenders into engagement with theaz-ngularly disposed gripping tongues 6 and The locking bar 8, holds thesuspender portion 1 in engagement with the tongues 6 and 7 and isdisposed between the tongues,

and to hold the locking barin such position, the locking plate 18 ismoved into engagement therewith and the spring catch 15 1 locked inengagement with" the bead 17.

Thus it Will be seen that the suspender por tion 1 is locked and thatmovement thereof relative to the device is prevented.

Thedevice may be stamped out of a suitable blank of metal. Thus it willbe seen that a reliable, eflicient and cheap adjusting lock is provided.y

In reduction to practice, we have found that the form of our invention,illustrated in the drawings. and referred to in the above description,as the preferred embodiment, is the most efiicient and practical; yetrealizing that the conditions concurrent With the adoption of our devicewill necessarily vary,

we desire to emphasize the fact that various minor changes in details ofconstruction, proportion and arrangement of parts may be resorted to,when required,.without sacrion said plate, a U-shaped locking bar havingits free ends bent angularly and pivoted in said ears, said bar adaptedto force thesuspender strap into engagement with the gripping tonguesand a rectangular locking plate hingedly secured at one end to one ofthe ends of said plate and arranged to engage and cover said U-shapedlocking bar tohold said bar in locked position. i g

In testimony whereof we aflix our signatures in presence'of twowitnesses.
